The Weald, covering ~10,000 km2 (3,900 mi2) of southeast England, is composed of a heavily eroded east-west anticline. It features a surface sometimes capped by gravel called "clay-with-flints," water and wind gaps through the chalk ridges on its flanks, and a local silcrete duricrust with eroded sarsen stones. Although uniformitarian scientists have offered several hypotheses to explain the geomorphology of this classical area, they all have major difficulties. We analyze these explanations and draw the following conclusion: The Weald’s geomorphology, like many other areas of the world, remains a uniformitarian mystery. It is better explained by rapid Genesis Flood runoff, not erosion over millions of years.
